What this test is

The swordfish allergy test measures specific IgE antibodies in your blood that react to proteins found in swordfish. It is used to help evaluate whether your immune system has become sensitized to this fish. The test is one part of a broader allergy assessment.

What it measures

  • Swordfish-specific IgE — Reflects the level of allergic antibodies directed against swordfish proteins.
  • Total IgE (sometimes) — May be measured to provide context for allergic antibody levels.
  • Other fish-specific IgE (if ordered) — Can help identify reactions to related fish species.

What the test involves

A healthcare professional collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test if you have had symptoms such as hives, swelling, or digestive upset after eating swordfish or other fish. It can also be used to help distinguish a true allergy from other causes of food-related reactions.

Preparation

No special preparation is usually required, but you should follow the instructions provided by the collection lab. Tell the lab about any medications you take, as some may affect test results.

How results are reported

Results are reported as a numerical value that indicates the level of specific IgE antibodies, along with the laboratory's reference range. Reference ranges vary by laboratory, so your result should be interpreted in the context of that lab's own ranges and your symptoms.

Before you go

  • Whether any medications you take could affect the test results.
  • If fasting or other preparation is required before the blood draw.
  • How and when you will receive your test results.
